Description of the intervention
The use of image guidance is widely set as an important tool for
managing diseases of the nose and paranasal sinuses by increasing
surgeons’ confidence and confirming anatomic locations in challenging
fields.12
The Image Guided Surgery (IGS) systems have the following items: a
computer, video monitor, tracking system, surgical instrumentation, and
data transfer hardware. The tracking system allows for the real-time
determination of the instrument location relative to anatomical
landmarks. Electromagnetic or optical tracking technology can be used to
perform this position determination in the operating field against
preoperative imaging data sets.3,20
